Tsui Hark said in Clearing Money, Agriculture, Industry and Commerce: "Thirty-six walkers, various occupations. As far as the division of labor is concerned, it is 36 lines, 72 lines, and 360 lines ten times. " It can be seen that "72 lines" is a virtual indicator, and the 72 lines or 360 lines that people often say today are not specific numbers. In fact, the division of labor in social industries has far exceeded the 72nd line.
Thirty-six lines introduction:
Thirty-six lines are a general term for all walks of life in the old society. Thirty-six lines are the general name of the main social industries in China in the Tang Dynasty, reflecting the division of labor of social industries at that time. Line 36 extends the industry classification theory of line 72 or line 360 commonly used in China. The exposition of thirty-six lines can be found in Hui Zhou's Qing Bo Zalu in the Song Dynasty. Tsui Hark said in "Clearing Banknotes and Farmers": "Thirty-six walkers, various occupations. According to the division of labor, it is 36 lines, 72 acts, and 360 acts ten times. " It can be seen that line 36 is only an imaginary indicator, not a specific number.
